Cariboo Rose, BRS drill 70 m of 0.31% CuEq at Cowtrail

Executive Summary

• BRS Resources Ltd. and Cariboo Rose Resources Ltd. announced results from a four‑hole, 1,138 m diamond drill program at the Cowtrail porphyry copper‑gold project in British Columbia.
• The program confirmed continued porphyry‑style Cu‑Au mineralization that remains open along strike and at depth across the Lea Lake zone.
• Historic intercepts and new data highlight a southwest‑trending mineralized corridor extending beyond the original 2007 discovery, supporting further exploration potential.

Key Details

• Program scope: Four holes totaling 1,138 m drilled in August 2025 targeting the Lea Lake zone’s induced‑polarization and magnetic anomalies.
• Historical significant intercepts (for context):
• 0.15 % Cu & 0.12 g/t Au over 105.0 m (CT23‑16, 2023)
• 0.17 % Cu & 0.11 g/t Au over 40.0 m (CT2011‑12, 2011)
• 1.16 g/t Au over 18.3 m (07‑DDH‑1, 2007)
• New drilling results: Confirmed continuation of porphyry Cu‑Au mineralization; specific assay values were not disclosed in the release but are reported as open‑ended and consistent with historic grades.
• CuEq calculation methodology: Uses $4.50/lb Cu and $3,500/oz Au without metallurgical recovery factors.
• Geology: Intrusive suite includes diorite, syenite, quartz, monzonite, and quartz‑feldspar porphyry; stockwork and dike structures identified over a ~3 km × 2 km area.
• Exploration potential: Numerous induced‑polarization anomalies remain untested; a 1991 Cogema report notes additional mineralized biotite/diorite/monzodiorite float associated with a strong circular total magnetic intensity anomaly further along the trend.
• Option agreement: Cowtrail is under option to BRS Resources (since 2022). BRS may earn a 60 % interest by completing $2 M in exploration expenditures, paying $200 k cash, and issuing shares equivalent to $200 k by 19 Dec 2027.
• Assay protocol: Samples analyzed by MSALABS (Langley, BC) using ICP multielement analysis and 30‑g fire assay; recoveries >85 %; QA/QC procedures included standards, blanks, and independent verification.
• Qualified Person: J.W. (Bill) Morton, P.Geo., director of Cariboo Rose Resources, NI 43‑101 qualified person, reviewed and approved the technical content.
